Hi,
This thread shows the making of a fold-over sheath for the Boot Shark knife kit.

This KnifeKits video features the process of making a fold-over style sheet with a small Tek-Lok. Holstex Raptor London Tan was chosen for this fixed blade sheath. With over 40 size and color options of Holstex and numerous attachments to choose from, this turned out to be a great match for the Boot Shark knife kit. This process can be adapted to make any DIY custom sheath
